Linglong-Jiaojia-type gold deposits in this paper deff erent from main research types of the world mean the pyrite quartz vein-phyllic altered cataclasite type occurring in shear zone of granites of Mesozoic. The material base of alteration-remelting of the granites comes mainly from a Precambrian sedimentary-metamorphic series containing intermediate-basic volcanics. Because of different properties of ore-containing and ore-forming structures, these deposits show two main forms or subspecies of mineralization. The Linglong-subtype (quartz vein-type) and the Jiaojia-subtype (veinlet-disseminated phyllic altered rock-type) appear to possess a horizontal zoning mainly.In the research field of deformation in combination with petrofacies change of rock, this paper deals with the following, defines a reversed"S"-shape for the arcuate fault-fold metamorphic petrofacies form extending in the E-W direction in the Jiaodong basement and a "N"-shape for the fault-basin tectonic petrofacies form, and puts forward that the compounding of their both formed the basic tectonic frame of regional minerogenesis; the granitoid related to gold mineralization is respectively assigned to the com-presso-shear structural petrofacies Linglong-type granite, the compressive structural petrofacies Guojialing-type granite and the tensile structural petrofacies Luanjiahe-type granite, whose these characteristics are coordinated with Indosino-Yanshanian movement in this area; according to research of geology, chemical composition, isotope and REE etc., classifies the Precambrian metamorphic rocks chiefly of the Jiaodong Group as the intermediate source series whose original submarine intermediate-basic volcanics and elastics are initial ore source series, and the granitoid formed by metasomatism and remelting of them is the direct ore source rocks; minerogenesis is related to shear zone and its subordinate component, as a general rule, Linglong-Jiaojia-type belongs to gold-bearing shear zone-type gold deposit (M. emaison et al. 1986). Studying their genesis of above phenomena of relationship close between structure and petrofacies, author sets up the theoretical and mathematical model, measures the palaeostress, The palaeopressure and other physicoche-mical parameters, emphatically on basis of viewpoint of "the affect of tecto-nodynamics on hydrostatic pressure", and demonstrates that the tectonic additional hydrostatic pressure is basic dynamic factor causing the change of chemical progress and element properties in petrofacies change during deformation of rock. Forthermore, puts forward that the tectonic additional hydrostatic pressure is regarded not only as the physical variable causing the change of rock volume, but also as a physicochemical parameter affecting chemical progress in the deformational rock.

玲珑-焦家式金矿是指胶东前寒武变质岩系内中生代花岗岩含金剪切带石英脉-绢英质蚀变岩金矿类型。由于赋矿及成矿构造性质不同,该类矿床可分为明显有别的两种典型矿床类别。区域成矿作用受中生代“N”形断陷构造-岩相形式与基底反“S”弧形断褶-变质岩相形式的复合控制。成矿是沉积→变质→交代和重熔作用发生发展的综合结果。开展矿源岩系(序)列研究,划分成矿花岗岩类为剪切、挤压及引张构造-岩浆岩相,并提出了室内外鉴别标志。 作者在对各层次岩石结构、形变与成分、相变等相关的地质事实研究基础上进一步探讨了成因,侧重以“构造作用力影响成岩成矿静水压力”的观点建立了理论、数学模型,实测了古应力、古压力及其它成矿物理化学参数,从而论证了构造附加静水压力是变形岩石发生相应相变的主要动力因素,构造附加静水压力不仅是使变形岩石体变的物理量,而且是影响、制约其中成岩成矿化学过程的物理化学参变量。

Stress state in the crust forms mainly Under the tectonic force and gravity. The author suggests that the hydrostatic pressure P of a point in the crust is a combination of two isotropic stresses in the stress field of both tectonic force and gravity. The former is referred to as a structural or tectonic additional hydrostatic pressure Ps and the latter as a gravity additional hydrostatic pressure PR·A formula of their relationship is listed below: where PRv is Poisson' s radio of rock, is density ofrock and...

Stress state in the crust forms mainly Under the tectonic force and gravity. The author suggests that the hydrostatic pressure P of a point in the crust is a combination of two isotropic stresses in the stress field of both tectonic force and gravity. The former is referred to as a structural or tectonic additional hydrostatic pressure Ps and the latter as a gravity additional hydrostatic pressure PR·A formula of their relationship is listed below: where PRv is Poisson' s radio of rock, is density ofrock and h is depth, or thickness of overlying rock.The calculations by the use of NOLM 83 (Wang Ken et al) in finite -element model of a horizontal plate under horizontal force indicate that the additional hydrostatic pressure by tectonic force gradually decreases in the given order in the compressive zone (Pcs),the shear zone (Pshs) and the tensile zone (Pts ) at the same depth.The horizontal force in the X direction is 10MPa, and that in the Y direction is 60 MPa. The σ1 and σ3 in elements are given in Table 2. The medium principal stresses can be calculated by plane strain problem, and each Ps in elements can be obtained (Fig- 3). The average values of P, in the different deformation zones are PC =30.3 MPa, Pshs = 27.24 MPa and Pts = 23.81 MPa.If the model horizontal plate is at a depth of 3.5km, and the force is 35 MPa in X direction and 85 MPa in Y direction, we get 3 principal stresses in elements.Because PR≈25 MPa in the reseach area,the average values of PS of each element group are Pcs = 25.02 MPa, Pshs = 23.31 MPa and Pts = 18.61 MPa after PR is reduced from average principal stresses (P). The difference between PC and Pshs becomes smaller, but the difference between them and Pts is bigger.This research explains an important theoretical problem about how the tectonic force effects the physicochemical environment of petrogenesis and metallogenesis, and is a theoretical basis of tectonic physicochemistry or te-ctonophy sicochemistry(Lu Guxian, 1991),which is a new branch or research field in geology.

地壳应力状态主要是由重力和构造作用力引起的,作者明确提出其静水压力部分是由重力所附加的静水压力和由构造作用力所附加的静水压力叠合而成。本文用有限元模型数学模拟实验证实,处在挤压变形带、剪切变形带到引张变形带(及地域)中岩石所承受的构造附加静水压力有逐次变小的规律性,利用这种规律可解释构造作用力影响成岩成矿作用的物理化学环境及制约其化学过程的动力学问题,为开展构造物理化学研究奠定了基础。

This paper argues against the knowledge that hydrostatic pressure is equal to the gravity value of the overlying rocks in studying a dynamic state of certain underground site, and discusses the influence of tectonic stress on hydrostatic pressure and its application.The research of solid mechanics and data from deep drillings indicated that gravity and tectonic stress in middle and shallow crust are directional external forces, whereas hydrostatic pressure is a force of non-directionless, so they possess different physical meanings. Gravity is not quantitatively equal to hydrostatic pressure either. During 108a- 106a of stress relaxation, the directional force on solild rock of the crust produces a deviatoric stress field.The authors suggest that stress field T of the crust is a combination or superposition of hydrostatic pressure P with differential stress a, and the total hydrostatic pressure P at any point in the crust comprises two parts, one is spherical stress tensor PR caused by the gravity and the other is spherical stress tensor Ps caused by tectonic stress, therefore P is not only from the gravity of overlying rocks.The results obtained by a finite element simulation indicate that the additional hydrostatic pressures borne by rocks decrease gradually from the compressive zone (P) to the shear zone (P) and to the tensile zone (P), i. e; and the difference of the tectonic additional hydrostatic pressure between these deformed zones trends to Increase, following the increase in absolute value and/or difference of external forces in different directions. So the tectonic additional hydrostatic pressre is a major factor causing the heterogeneity of local stress field in the same depth of the crust.The above-mentioned research has a wide-range of application= 1) to set up a model of unequal hydrostatic pressures in same depth of the crust; 2) to establish the method of measurement of metallogenetic depth corrected by structure, i. e., firstly minute toctonic added hydrostatic pressure P. from general hydrostatic pressute P, then measure and calculate thedepth data of overlying rocks; 3 ) to get Into a new research field of tectonic physicochemlstry; 4) reconsider the depth of eclogite in superhigh pressure metamorphic zone, such as the knowledge that the diamond and coesite in Dabie tectonic-metamorphic zone are probably the products of the inner crust; and 5) to introduce some new ideas about experiments of chemical kinetics.

本文对于“上覆岩石重力数值等同于静水压力数值”的认识提出了新的看法:地壳中应力场T可以看成是一个静水压力P和一个差应力σ的复合,则静水压力P是由重力附加静水压力PR和构造力附加静水压力Ps两者叠合而成,而不仅仅是来自上覆岩石的总重量。有限元模型计算表明,在同样外力条件下,从挤压变形带、剪切变形带到引张变形带中的各带构造附加静水压力值呈降低变化,即,因而构造附加静水压力是造成局部静水压力不均匀的主要因素之一。通过这一问题研究,作者提出:①地壳深处同一水平面上静水压力并不相等;②建立“构造校正成矿深度测算”方法,即先从总压力中消除构造附加静水压力之后再测算上覆岩石厚度;③研究成岩成矿构造物理化学过程的学科领域;④苏鲁超高压变质带中的金刚石、柯石英可能是壳内作用的产物;⑤介绍开展实验的新设想;⑥报道用构造物理化学场成矿理论开展隐伏矿床预测的进展。
